Elastic Slide Rail Bracket for Single-Person Rack Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies require two people to mount and are limited in compatibility with racks of varying depths due to restrictive blocking mechanisms, lacking convenience and adaptability.
Innovation Solution
A slide rail assembly with a detachable bracket device featuring an elastic member that allows for single-person mounting and detachment, and adjustable length options to accommodate different rack depths by blocking and unblocking mechanisms corresponding to wall portions of a rail member's space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blocking mechanism is used to prevent displacement between bracket and rail, then safety is improved, but the blocking function provides blockage in one direction only requiring two people for mounting
Solution Approach 1:
The elastic member changes its blocking parameters based on displacement direction. It provides strong blocking force in the first direction (preventing accidental detachment) while allowing easy displacement in the second direction (enabling single-person mounting). This parameter change resolves the contradiction by making the blocking function directional rather than uniform.
Solution Approach 2:
The elastic member transitions from a static blocking mechanism to a dynamic one that responds to applied forces. When force is applied in the first direction, it engages blocking; when force is applied in the second direction beyond a threshold, it disengages blocking. This dynamic behavior enables both safety and ease of operation.
2Strength
If a fixed-length rail is used in slide rail assembly, then mounting strength is ensured, but it cannot be mounted on racks with depths outside a certain range
Solution Approach 1:
The bracket device is divided into modular components including the rail member and detachable bracket, allowing the overall length to be adjusted by replacing components. This segmentation enables adaptation to different rack depths while maintaining proper mounting strength through appropriate component selection.
Solution Approach 2:
The slide rail assembly is designed with universal mounting features that allow it to function with racks of varying depths. The detachable bracket and adjustable rail configuration enable the same basic assembly to serve multiple rack depth requirements, achieving versatility without sacrificing mounting strength.
3Reliability
If an elastic member with blocking sections is used, then bidirectional displacement prevention is achieved, but the structure becomes more complex
Solution Approach 1:
The elastic member integrates multiple functions into a single component: it provides blocking in the first direction, allows controlled displacement in the second direction, and incorporates guiding features for alignment. By merging these functions into one element rather than using separate mechanisms, the structure achieves bidirectional control without excessive complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient single-person installation and removal, and adaptability to various rack depths through the use of an elastic member that blocks or releases to allow longitudinal displacement, enhancing usability and compatibility.
Implementation Method 1
One of the first structure and the second structure is an elastic member. When the first structure and the second structure are blocked by each other, and the external force applied to effect relative displacement between the first bracket device and the rail member is less than the force generated by the elastic member, the first bracket device and the rail member are prevented from being displaced with respect to each other
Implementation Method 2
the elastic member is configured to be operated so as to stop blocking, and being blocked by, the other of the first structure and the second structure, thereby allowing the first bracket device and the rail member to be displaced with respect to each other

AI summary
A slide rail assembly includes a rail member ad a bracket device. The bracket device can be displaced with respect to the rail member and is provided with a first structure. The rail member is provided with a second structure. When the bracket device is at a predetermined position with respect to the rail member, the first structure and the second structure are blocked by each other to prevent the bracket device from being displaced with respect to the rail member in either of a first direction and a second direction.
